My MacBook Pro is suddenly getting fake Adobe Flash update popups multiple times a day
I'm on a MacBook Pro running Yosemite.
Every time I use Chrome, I suddenly get a popup in a new window that prompts me to update my Flash player. The web address is clearly fake (oftentimes it's go.mobifoth.com and then it redirects to a clearly fake Adobe page before sending me over to another ad page). This also happens frequently when I try to open a new tab.
Here is one of the links it directs me to: http://lastworking.ourbestupgrade.bid./0Jgt4WqQUBv0tVeMUHniM0OyIkXbp6K22AbOLyi5H Oo./?&cid=322262454903&sid=1195625&v_id=…
And I've also attached a screenshot of what it looks like. I've gone into the Chrome Extensions and seen nothing there. I've looked for some rogue process in the Activity Monitor but I'm actually not sure what I should be looking for.
